Investment accelerates commitment to securing
cloud email environments with advanced protection, visibility, and
control
WASHINGTON, April 24,
2024 /PRNewswire/ -- Sublime Security, the
AI-powered, programmable email security platform, announced today
that it has raised $20 million in
Series A funding, led by Index Ventures with participation from
previous investors Decibel Partners and Slow Ventures.
Cybersecurity visionary and Crowdstrike Co-founder & former
CTO Dmitri Alperovitch is also joining the investment round
and Board of Directors. The added funding will be used to further
invest in the platform and improve the customer experience. In a
rapidly evolving threat landscape, email remains a top security
concern for businesses. Sublime gives security teams the ability to
detect and prevent these attacks with out-of-the-box protection and
unprecedented visibility into their cloud email environments, with
additional controls for customized detections, attack surface
reduction, threat hunting, and more.
Increasing financial impact
According to the most recent 2023 FBI Internet Crime Report,
Business Email Compromise (BEC) accounted for over $2.9 billion in losses, although the actual
number is likely much higher due to underreporting. The volume and
scope of attacks are escalating as bad actors deploy large language
models (LLMs) to wage advanced and varied malicious attacks that
include BEC, QR code phishing, extortion, malware/ransomware,
fraud, spam, and more.
Email security that's not a black box
Email security has traditionally been driven by vendors that
offer black box, one-size-fits-all solutions. However, security
teams can no longer afford to wait weeks or months for vendors to
address false positives or missed attacks, during which time
legitimate emails continue to get blocked and the same attack
campaigns continue to land successfully.
As the email threat landscape continues to evolve rapidly,
defensive tools must be equally adaptable. Sublime's AI-powered
detection engine gives teams visibility, transparency, and
ultimately control to protect their organizations against complex
email-borne attacks, unlike the traditional black box approach.
"On the offense, Generative AI enables attackers to rapidly
create diverse, sophisticated campaigns at scale, but on the
defense, it's a powerful tool for automated detection, triage, and
explainability," said Josh Kamdjou, Founder and CEO of Sublime
Security. "The Sublime Platform is a modern take on email security
that delivers immediate out-of-the-box protection, with the added
ability for teams to tailor email security controls to fit
organizational needs and benefit from community-driven protections
as the threat landscape evolves."
Historically, defenders have had difficulty exercising
meaningful control or collaborating within the email domain due to
a lack of tooling and common language for expressing complex
attacker behavior. Sublime's Core Detections are open source
on GitHub where anyone can contribute to and benefit from new
protections against the latest threats. Advanced teams that want
granular control to tailor detections, create exclusions, or
mitigate false positives for their organization also have access to
Sublime's detection engine with a purpose-built domain-specific
language (DSL), Message Query Language (MQL), which works
universally across Microsoft 365 and Google Workspace via API
integrations.
Kamdjou spent 10 years at the Department of Defense engaged in
various offensive cyber initiatives and also worked in the private
sector as a red teamer. Email phishing was always the easiest way
for him to gain initial access to a system, and he set out to build
a product capable of stopping him. Co-founder and COO Ian Thiel was an early team member at Optimizely
and most recently led growth at Alto. The team publicly launched
Sublime in February 2023 and the
platform is already experiencing significant demand and impressive
traction, with customers including some of the world's top security
teams at Spotify, Ramp, Vanta, Brex, Centrica, and others.
"Email security has become a high priority for businesses as
they face GenAI-powered attacks, and we believe that Sublime's
impressive technology, the founders' backgrounds, and their unique
go-to-market strategy put them in a strong position to tackle this
problem," said Jahanvi Sardana,
Partner at Index Ventures. "Sublime is pioneering a bottoms-up,
security practitioner-led approach that promotes community-driven
collaboration, and given the massive market opportunity for email
security, we are excited to see Sublime continue its trajectory of
hyper-growth."
In addition to the funding, Sublime is also announcing the
launch of Attack Score, its latest feature that uses transparent,
explainable machine learning to prioritize email threats. Attack
Score aids security analysts in quickly understanding and
prioritizing detected threats based on the detailed context of
observed attack indicators. Security teams have full control over
Sublime's Attack Score output, enabling them to combine it with
other logic using detection-as-code.
Sublime's Core Platform can be self-hosted for free at any
scale, and the first 100 inboxes are also free in Sublime's hosted
SaaS environment. For more information, visit:
